Guidelines for the psychological treatment of psychosis and substance use suggest integrated treatments to address both problems are necessary. One such treatment combines cognitive-behaviour therapy (CBT) and motivational interviewing (MI). While there are a number of scales to assess treatment fidelity to CBT and MI separately, none, to date, assess fidelity to integrated MI and CBT (MI-CBT) for psychosis and substance use.
This study aimed to develop a reliable and valid scale to assess fidelity to MI-CBT for people with psychosis and problematic substance use.
Items for a new scale (the MI-CTS fidelity scale) were selected from multiple relevant sources. Inter-rater reliability and validity (against the CTS-Psy and Motivational Interviewing Treatment Integrity (MITI)) scales were investigated.
The scale had good inter-rater reliability when used to rate adherence versus non-adherence. In relation to validity, the scale related well to CBT and MI scales (the CTS-Psy and MITI).
The MI-CTS is useful for assessing adherence to integrated MI-CBT for psychosis and substance misuse and could aid training and implementation of the approach.
精神疾病和物质使用的心理治疗指南建议，需要综合治疗来同时解决这两个问题。其中一种治疗方法结合了认知行为疗法（CBT）和动机访谈（MI）。虽然有许多量表可以分别评估 CBT 和 MI 的治疗一致性，但迄今为止，还没有评估针对精神疾病和物质使用的综合 MI 和 CBT（MI-CBT）的一致性的量表。
本研究旨在开发一种可靠和有效的量表，以评估针对有精神疾病和物质使用问题的人的 MI-CBT 一致性。
从多个相关来源中选择了一个新量表（MI-CTS 一致性量表）的项目。研究了其评估一致性和有效性（与 CTS-Psy 和动机访谈治疗完整性量表（MITI））的指标。
该量表在评估依从性与不依从性时具有良好的评分者间可靠性。在有效性方面，该量表与 CBT 和 MI 量表（CTS-Psy 和 MITI）相关良好。
MI-CTS 可用于评估针对精神疾病和物质滥用的综合 MI-CBT 的依从性，并有助于培训和实施该方法。
